3 Claims.

This invention relatesto an improvement in branch-fittings for Water-tubes and the like, such as Ts and crosses, and particularly toI branchfittings in which a so-called line-member and a so-called branch-member are independently formed so as to be assemblable on the job if desired, to meet the necessities of varied installation requirements.

The main object of this invention is to provide a branch-fitting of the character referred to with means for facilitating the assembly of the parts in their correct relationship. v

With the above and other objects in view as will appear from the following, my invention consists in a branch-fitting characterized by a tribular line-member and a complementary branchmember, each independently formed and assemblable together to form a branch-fitting and each provided with positioning-means engageable with the positioning-means upon the other member for locating the two said members with respect to each other.

My invention further consists in a branch-ntting characterized as above and having certain details of construction and arrangements of parts as will be hereinafter described and particularly recited in the claims.

1n the accompanying drawing:

Fig. l is a side view of a branch-tting embodying my invention, in the form of a'T;

Fig. 2 is a vertical central-longitudinal sectional view thereof;

Fig. 3 is a transverse sectional view taken on the line 3--3 of Fig. 1;

Fig. e is a View partly in side elevation and partly in longitudinal section of the line-mem ber of the branch-fitting shown in the preced-I ing ngures;

Fig. 5 is a top or plan View thereof;

Fig. 6 is a view partly in side elevation and partly in longitudinal section of a branch .member adapted to be assembled with a line-member ci the type shown in Figs. 7i and 5;

Fig. 'l is a top or plan view thereof;

li'ig. 8 is a vertical central-longitudinal sectional view ci a T constructed in accordance with invention and showing other forms which the positioning-means may assume; and y Fig. 9 is a transverse sectional view illustrating still another ier-m which the positioning-teens may assume.

1n the embodiment of my invention herein chosen for illustration in Figs. l 'to i inclusive, employ what E shall for convenience ci descripfA tion designate as line-member it, which in the particular gures referred to, is bell-mouthed at its respective opposite ends to provide sockets 11 and 12 for the telescopic reception respective ly of line-tubes or pipes. About midway between its respective bell-mouthed ends 11 and 12, the periphery of the line-member 10 is formed, either at the time of manufacture or by the workman on the job, with a lateral opening or port 13,-With which latter the flow-passage in a branch-member is adapted to be registered as will be hereinafter described.

Located on opposite sides of the port 13 and adjacent the bell-mouthed sockets 1l and 12 of the line-member, are a pair of complementary positioning-holes 14 and 15, which are adapted to receive respectively, and engage against the outer surface of, complementary bosses 16 and 17, downwardly pressed out from the under=sur= face of the saddle-portion 18 of what I shall for convenience of description designate as a branch-member 19.

The saddle-portion oi the branch-member is curved to snugly t the periphery of the line= member lo and is provided with a tubular projection 20 which is adapted to be registered with the lateral opening or port 13 in the line-member and to provide for the connection of a branch tube or pipe. Preferably, the tubular projection 20 of the branch-member is provided internaly with anannular stop-bead 21 against which a branch-tube is adapted to be seated.

Preferably, the line-members and the saddlemembers will be made in various sizes and types capable of being assembled together (i. e., a linemember and a branch-member) y A line-member and a branch-member are pref erably assembled together by solder and in the form of branch-ttings shown in Figs. l to 7 ine1 clusive, the bosses 16 and 17 respectively of the branch-member are seated in the periorations le and 15 in the line-member so that the said branch-member may be definitely located 'with respect to the port i3v after which the applicau tion of solder or brazing material will serve to permanently anchor the two members together.

The locating-means with which each oi the complementary members of my improved branchiltting are prcvidedmay assume a vaiiety of for instance, instead ci forming one or more per= iorations in the line-member, l may desired,

form the saddle-portion le of the branchmember with a perforation such as 22 in fi, pro= vide the line-member with a complementary preesed=out 'upstanding cr boss iitting within, and having its outer surface engaged by, the perforation 22 just referred to. l

If desired, the saddle-member may be upset to form a downwardly-facing socket 24 for the reception of an upstanding boss or nib 25 formed upon the periphery of the line-member, as shown in the right-hand portion of Fig. 8, in which gure the line-member is of' the type known as male-to-female inasmuch as it is provided with but one bell-mouth 12 and has its opposite end 26 left plain as shown, for telescopically tting Within another fitting.

In Fig. 9 I have shown the line-member 10 formed at substantially diametrically opposite points with bosses or ribs 27 and 28 which are positioned to engage respectively the lower edges 29 and 30.0f the saddle-portion 18 of the branchmember so as to position the latter upon the linemember.

It will be understood by those skilled in the art that my invention may assume Varied physical forms without-departing from my invention concept and I, therefore, do not limit myself to the specific embodiment herein chosen for illustration, but only as indicated in the appended claims.

Iclaim:

1. A metal branch-fitting for tube installations comprising: a tubular line-member having a saddle-receiving portion intermediate its ends, said saddle-receiving portion -being provided with a lateral port; a tubular branch-member having a saddle-portion at one end Ipreformed independently of the line-member to t the intermediate saddle-receiving portion of the said linemember over an area surrounding the said lateral port and to be joined thereto by soldering or the like; one of said. members being provided with integral means comprising a pressed-out boss adapted to have a portion of its surface engage an integral abutment on the other member to relatively position said members with said lateral port registering with the opening of the tubular branch-member.

2. A metal branch-litting for tube installations comprising: a tubular line-member having a saddle-receiving portion intermediate its ends, said saddle-receiving portion being provided with a lateral port; a tubular branch-member having a saddle-portion at one end preformed independently o'f the line-member to t the intermediate saddle-receiving portion of the said linemember over an area surrounding the said lateral port and to be joined thereto by soldering or the like; the saddle-portion of the branch-member and the underlying saddle-receiving portion of the line-member being provided with integral complementary means interengageable to relatively position said members with said lateral ports registering with the opening of the tubular branch-member, said interengageable means comprising a boss on one of said members and a socketon the other member.

3. A metal branch-fitting for tube installations comprising: a tubular line-member having a saddie-receiving portion intermediate its ends, said saddle-receiving portion being provided with a lateral port; a tubular branch-member having a saddlevportion at one end preformed independently of the line-member to fit the intermediate saddle-receiving portion of the said linemember over an area surrounding the said lateral port and to be joined thereto by soldering or the like; the saddle-portion of the branch-member and the underlying saddle-receiving portion of the line-member being provided with integral complementary means interengageable to relatively position said members with said lateral ports registering with the opening of the tubular branch-member, said interengageable means comprising a boss on one of said members and a perforations in the other member.
